Description
Technical field
This utility model relates to a kind of valve, is specifically related to a kind of air relief valve.
Background technology
At present, air relief valve is generally installed on high-temperature high-pressure apparatus, when the gas pressure in these equipment is too high, will be gone out by air relief valve overflow discharge, but owing to these gases emitted are usually high-temperature high-pressure state, therefore directly discharge, it is easy to follow-up reception equipment is damaged.
Summary of the invention
For the deficiencies in the prior art, this utility model provides a kind of air relief valve that can effectively reduce temperature of exhaust gas and pressure.
For achieving the above object, this utility model provides a kind of air relief valve, include valve body, valve gap, valve rod, flap, valve seat, described valve body is provided with entrance point and the port of export, connected by body cavity between entrance point and the port of export, described valve seat is installed on body cavity, described valve rod is coaxially located in valve seat, described flap is packed on valve rod lower end, and sealing can be correspondingly formed with valve seat, the upper end of described valve rod is fixed with piston, on described valve body, correspondence is fixed with the cylinder sleeve for the sliding within it of described piston, feedback runner it is additionally provided with between described cylinder sleeve and valve outlet end, described valve gap is installed on valve body, spring and spring capping it is provided with in valve gap, the upper end of described spring abuts with spring capping, the lower end of described spring is resisted against on piston, described valve gap is also equipped with an adjustment screw for regulating spring pressure, described adjustment screw is pressed on spring capping, it is provided with an adapter sleeve in the port of export port of described valve body, the inner ring surface of described adapter sleeve keeps connecting with body cavity, and the inner ring surface of described adapter sleeve is connected and composed by one section of cylindroid and one section of taper surface, described cylindroid is positioned at outer end, described taper surface is positioned at the inner, the bigger diameter end of described taper surface connects with cylindroid, and the diameter of described cylindroid is identical with the bigger diameter end diameter of described taper surface, described adapter sleeve is additionally provided with coolant circulatory flow around described cylindroid.
The beneficial effects of the utility model are: adopt said structure, owing to this utility model is provided with an adapter sleeve in the port of export port of described valve body, and the inner ring surface of described adapter sleeve is connected and composed by one section of cylindroid and one section of taper surface, described cylindroid is positioned at outer end, described taper surface is positioned at the inner, therefore the gas emitted can first pass through described taper surface, after through described cylindroid, so arrange, can effectively slow down the flow velocity of discharge gas, the pressure making gas is gradually lowered, simultaneously because described adapter sleeve is additionally provided with coolant circulatory flow around described cylindroid, therefore the coolant that also can be cooled in liquid recycle stream road by the heat of the gas of cylindroid absorbs gradually, so that the temperature of gas is gradually lowered, finally emit with low temperature, so can be prevented effectively from and follow-up reception equipment is damaged.
This utility model can be further arranged between described adapter sleeve and valve outlet end port and be additionally provided with sealing ring.
